I filed AVRO-150 for this.
> Speed up ivy resolution in builds with clever caching

> An awful lot of time is spent in the ivy:resolve parts of the build, even when all of
the dependencies have been fetched and cached. Profiling showed this was in XML parsing. I
have a sort-of-ugly hack which speeds up incremental compiles (and more importantly "ant test")
significantly using some ant macros to cache the resolved classpaths.
